A mother ship (or mothership) is a vehicle (e.g. ship, aircraft or spacecraft) that leads, serves or carries other, usually smaller vehicles. The concept of a mother ship has achieved prominence in science fiction and UFO lore, extending the idea to spaceships that serve as the equivalent of flagships among a fleet. In this context, mother ship is often spelled as one word: mothership. A mothership may be large enough that its body contains a station for the rest of the fleet.
So, are you ready to make your own Alien Mothership?!
